Fast food giant McDonald’s has shed some light on the way it make its food by answering some of the more uncomfortable FAQs posted on its U.S. website.

In an attempt to be more transparent, McDonald’s answer queries on a page of the U.S. site called Your Questions Answered, where it says it is ‘important to provide you with honest, straightforward facts’ before listing some of the most frequently asked questions about its food sourcing and processing methods, both of which have often been criticised.

The restaurant answers a variety of questions that range from the innocent (‘what oil do you cook with?’, to the bizarre (‘do you use ‘pink slime’ in your burgers?’)

One of the more worrying frequently asked questions reads: ‘Is the McRib made using the same plastics as yoga mats?’

McDonald’s answer is that a variation of an ingredient used in the iconic (and delicious) burger is in yoga mats, but it is ‘simply not true’ that the food ‘contains that same rubber of plastics.’

The company tried to explain where some of the worries surrounding McDonald’s food come from.

It said: ‘We recognize the difference between using ingredients in food versus using a variation of those ingredients for non-food purposes can be confusing.

‘We also realize that sometimes the scientific name of an ingredient may sound scary.

‘For example, the salt you use to de-ice a driveway is a variation of the salt you use in the kitchen, however they are both sodium chloride.’
